Abstract
The coupling of dislocations and ledges in phase transformations is co nsidered in terms of the symmetry of phases meeting at an interface. G rowth and structural ledges and a variety of dislocation arrays are tr eated. Symmetry and the absence of long-range strain fields alone are shown to produce few restrictions on possible interface structures.
